Sure sounds interesting and I can feel a demo coming on.
Somethings a few demo hours can't answer easily like:
1. Comfort for rider and pillion - especially the pillion seat?
No complaints from the Mrs regarding the pillion seat. And no complaints from me in respect of the riders seat ( I used an airhawk on my GS )
2. Honda panniers. Are the waterproof?
My own opinion is that the OEM panniers are crappy plastic, I use Givi Outback 37L alloy ones. The OEM top box leaked, it was redesigned last year.
